Determine the half life of radium 226
WebThe half-life of radon-222 is 3.8 days, so some radon atoms can travel a long distance through the atmosphere before decaying to nonradioactive lead-210. The radon decay process involves seven principal decay products before ending with lead, a … WebWhen radium-226 decays radioactively, it emits an alpha particle (the nucleus of helium), and the end product is radon-222. This decay can be modeled by thinking of the radium-226 as consisting of an alpha particle emitted from the surface of the spherica. The nucleus of an americium atom contains 146 neutrons and 95 protons.
